I've made a lot of changes to it including allowing on-map filtering and adding a new interface. I have some other ideas, but I'd like to get some feedback on what /r/Atlanta would like to see.

EDIT: Thanks for all the input. I've made a few changes based on it already. There are now tooltips when hovering over the projects on the map, and instead of opening a new tab when you click, it will scroll to the relevant project in the toolbar on the left. Enjoy!

Put the info about specific projects on the map itself (as a pop up), rather than opening a new tab (EDIT:Looks like you can access this info through the sidebar, which then points you to the place, but it'd also be useful to do this the opposite way by clicking on the polygon itself. Right now, clicking on something just directs you to another page, but I'd prefer to be access the project info this way. You already have the link in the info, which I think is enough).

Also, maybe you could organize the sidebar better, e.g., according to neighborhoods?

While it can use a few tweaks, this effort is much appreciated! I've been doing something similar to this for a while using google maps, but nothing this organized. So yeah, thanks for doing the dirty work for us!

If you look at more recent maps there are actually 2 or 3 different options for getting the beltline across Dekalb and the multi-modal yard along it. Of these, I think the option I highlighted is the most likely for several reasons. It wouldn't require tunneling, or finding some other way of crossing an active freight yard, and it runs along Memorial. Both the city and the state are interested in reviving the Memorial corridor and I think that makes this option attractive.
